Victoria Justice is super excited to be on tour with Big Time Rush! Even though she's focusing on her music now, she doesn't forget her roots -- which are with Victorious!

Since Victoria's a veteran in the biz (even though she's still so young!), we asked her what advice she has for her former co-stars Ariana Grande and Jennette McCurdy as they embark on their Victorious spinoff, Sam & Cat.

"I know at least when I was filming Victorious I was working nonstop and recording, and it gets crazy when you're filming your own show," she told M exclusively. "So I would tell both of them to take for yourself, chill with your family, and just kind of re-center. Because it can get kind of crazy and hectic!"

Victoria's wise words will especially be useful to Ariana, since she's a busy little bee with her music career too!
